BODY-FORMING iyrnonanrs a.

Application filed October This invention relates to body-forming machines such as are used for the produc tion of bodies, as tin cans, from a blank of sheet material; and has for its main objectand feature the production of means for more accurately controlling the blank on .the horn.

Accordingly, .the inventionconsists of the hereinafter described features of construc- Io tion, combination of parts, nd arrangement of elements. v I

In the accompanying drawings, the invention is disclosed a concrete and preferred form in which:

Fig. l is a general end view of the horn and "the body-forming members associated therewith together with the support for said body-forming members:

Fig. 2 is an enlarged View of the support for the body-forming members and associated elements, the body-forming members being omitted in this figure: r

Fig. 3 is a side elevation, partly in section, of the members shown in Fig. 2 and looking in the direction of arrow f Fig. 2:

Fig. 4- is a vertical sectional view in the plane of line 4 4 of Fig.8; v

Fig. 5 is a detail end view of the horn and bumper:

Fig. 6 isa transverse sectional view in the plane of line 66 of Fig. 7:

' Fig.7 isa side elevation, partly 111580171011, of the horn shown in Fig. 5, showing said horn in expanded position: and f Fig. 8 is a view substantially the same as that ofFig. 7 but with the horn in its collapsed position.

1 indicates a horn suitably sustained in the machine and adjacent thereto is a support '2 on which'is pivotally carried at 3 body- Tforming members 4 of any desired construction. 5 indicate rods for actuating the bodyforming members to fold the blank around the horn in a manner well understood. vThe horn is composed of a number of parts,,here two in number and indicated by 6 and 7 that ,isto say, the horn consists of two com- ;plementary halves suitably, connected together and normally urged into a collapsed position by suitable meanssuchas springs 8. Suitable cam means are provided for expanding the horn and for permitting the 9, was. Serial No. 1,454.

springs to collapse it; and, in the present instance, these fmeans take the following form. 9 is a stationary cam membertarried by part 6 of the horn andhavi'ng a number Y of cam faces, sucha's 10, space'd'l'engthwise within the horn. 11 indicates a slidable cam member having cam surfaces 12 correspond ing with faces l O;"an'd this cam menibenl l eirtends lengthwise within the horn and sl des upon'the part '7 thereof. 'Suitable means 'are'provided for reciprocating member 11 and these means are conventionally represented by .rod 18 and lever 14. The 5 movement of lever 14 being a timed one, it i will be seen that boththeezipanding'andcollapsing movement ofthe horn'istimed and positively controlled because spring 8 cannot collapse the horn mor e rapic'lly'than the 7 cam means will admit of.f15' indicates a clamping member arranged "between" the body-formingmembers and slidably mounted in support 2 by' means of pins'16 orotherwise. Associated with this clamp'ing'mem- 1 her is a rod 17 extending vertically through the central bar 18 of support 2, said rod having at its upper end ataper' surface 19; and suitable spring means, such as 20, are provided whereby said 'spring means n0rmally tend to urge the member 17 away from the surface of the horn. Timed mechanism, here represented as a rocking arm 21, is provided; and connected tot-his rocking arm is an actuating rod 22 slidably mountedin the support 2 and having taper surface 23,"complementary to taper surface .19, whereby it will be understood that when arml21 is moved to the left (Fig: 3), rod 17 will be depressed against the action of spring 20 and the clamping-member will firmly engage the surface vof .the horn. To steady and assist in guiding rod 17, there may be provided a guidebolt 24 that extends through a slot in'rod 1 7. Suitable gauging means are provided for meeting the frontjor leading edge of'the'incomingblank"and to properly position on the horn; and theselmeans, i'nthe [resent instance, take thefollowingiforin. 25 indicate two slides, but" at ,eitherfside of'ftjhe clamping member, movable in guides 26 'fof support 2; and th s car y sauc Jmembers 27fwhi0 Qm adjac t t eijlgc and register the sheets as they come into position. Slides 25 are preferably carried on support 2 by means of slots 28 and pins 29, and means are provided to yield to and also to resist the impact of the blank that here assumes conveniently the form of a spring 30 carried by support 2 and acting to draw cross-bar 31 that connects both slides 25 in a direction opposite to that of the feeding movement of the blank.

It will now be understood that when a blank is fed in the usual way lengthwise to the horn, the latter is in its collapsed position and said blank comes against gauges 2 that register it, after which the clamping member descends and clamps the blank in position on the horn. Body-forming members now descend and fold the blank around the horn thereby at the same time, bringing said blank out of the way of the gauges; and after the hooks of the blank are interlocked and the horn is expanded, bumper 3Q rises and closes the seam.

I claim:

1. Body-forming mechanism including: a horn, body-forming members to fold a blank around the horn, a clamping member above the horn and intermediate the body-forming members to engage a blank on the horn before it is acted upon by said body-forming members, spring means for normally urging said clamping member away from the horn, and timed mechanism to overcome the action of the spring means tothereby bring the clamping member toward the horn.

2. Body-forming mechanism including: a

horm body-forming members to fold a blank around the horn, a clamping member above the horn and intermediate the bodyforming members to engage a blank on the horn be fore it is acted upon by said body-forming members, a rod connected with said clamping member, spring means normally urging said clamping member away from the horn, an actuating rod at an angle to the first rod, and complementary taper surfaces on the two rods for imparting motion from the actuating rod to the clamping member to overcome the action of the spring means.

3. Body-forming mechanism including: a horn, body-forming members to fold a blank around the horn, gauges above the horn and intermediate the body-forming members to receive the front edge of a blank fed lengthwise of the horn, and supporting means adapted to yield in the direction of the feeding movement of the blank.

a. Body-forming mechanism including: a horn, body-forming members to fold a blank around the horn, aclamping member above the horn and intermediate the body-forming members to engage the blank on the horn before it is acted upon by said body-forming members and gauges above the horn at either side of the clamping member and also intermediate the body-forming members to receive the front edge of a blank fed lengthwise of the horn.

6. Body-forming mechanism including: a horn, body-forming members to fold a blank around the horn, a clamping member above the horn and intermediate the body-forming members to engage a blank on the horn before it is acted upon by said body-forming members, spring means for normally urging said clamping member away from the horn, timed mechanism to overcome the action of the spring means to thereby bring the clamping member toward the horn, and gauges above the born at either side of the clamping member and also intermediate the bodyforming members toreceive the front edge of a blank fed lengthwise of the horn.

9. Body-forming mechanism including: a horn asupport above the horn, body-forming members pivotally connected with said support, a clamping member carried by said support above the horn and intermediate the body-forming members to engage a blank on the born before it is acted upon by said body-forming members, spring means to normally urge said clamping member away from the horn, and timed mechanism extending through said support to overcome the action of the spring means to thereby bring the clamping member to the horn.
